Spraying in tight corners

[woodferret]

I've been re-building out a window trim lately and am finding myself very tight to some walls on some of the perimeter casing (~1-3 inches away).  These are craftsman style so mostly block 90 faces that directly oppose the walls in question, making the angle to get in there even worse.

My question is how one would spray these (4stage HVLP)? 

I'm currently using BIN, HSF5000, and then a top of EM6500 tinted lacquer.  I'm almost tempted to
- pre-finish the perimeter edges to the corner, masking the rest
- tack it back up, fill all holes, and touch up BIN
- knockback the corner slightly with sandpaper, and mask the existing pre-finished portions.
- Then start the series of sprays with HSF and topcoat.

Alternative Plan B is to just put it up, spray as normal and touchup brush the offending perimeter faces by hand as needed.

Anyone have experiencing finishing these types of tricky areas?  Thanks.

I don’t have any tips on spraying but I’m doing craftsman style trim on the windows in my house, but I want to see the wood so I’m pre-finishing the parts with wipe on poly.

I have stage 4 spray equipment. 

My only comment is that I am currently refacing all the kitchen cabinets.  I have been spraying the doors, drawers and end panels in the shop.  I’ve been brush painting the face frame in situ. 

I’ve been using Benjamin Moore’s Advance, a very slow drying paint.  The slow drying aspect allows for self-leveling.  Advance, in high gloss, is rated for outdoors use (but none of the other glosses are).

Also, Fine Paints of Europe makes exceptional oil based paints that also dry slowly and is reputed to dry to an exceptionally fine finish and super durable.  I have not used this stuff, but plenty is written about it online.  It is supposed to be the ultimate door and window paint.  It is available in exceptionally high gloss finish if that is what you are after.

Again, I would brush on. 

In all cases, I would paint when there is no direct sun.  The direct sun will hasten drying times and minimize the self-leveling properties. 

For me, this is a brush on application. 

Note:  There are window masking spray on films, that also act as primers.  You brush or spray on the film and you can peal off easily any overspray or over brush.  If you get some on the window too, no problem.  It acts as a primer on other surfaces.
